IMBRUVICA® may cause serious side effects, including1:

- Muscle spasms
- Low red blood cell count (anemia)

In the adult and pediatric cGVHD clinical trials, nearly 1 in 4 of patients stopped taking IMBRUVICA® because of side effects.1
This is not a complete list of side effects. Others may occur. Tell your doctor if you think you are experiencing side effects.
If you are having some side effects, your doctor may tell you to lower your dose or to stop taking IMBRUVICA®. That’s one reason it’s so important to tell your healthcare team about side effects at any point in your treatment.1
You may experience side effects while taking IMBRUVICA®.1 The suggestions below may help you while on IMBRUVICA®. Talk to your healthcare provider if you think you are experiencing any side effects.
Diarrhea can be an uncomfortable side effect for patients taking IMBRUVICA®. It can also be a sign your cGVHD is getting worse.3 So be sure to contact your doctor right away if you develop this symptom. In the meantime, there are also some tips that can help you manage your condition:
- Stay hydrated. Drink fluids such as water, decaffeinated tea, and clear broth
- Eat small meals often, and avoid very hot or spicy foods
- Avoid greasy foods, bran, raw fruits and vegetables, and caffeine
- Avoid alcohol and tobacco
Diarrhea is a common side effect in people who take IMBRUVICA®. Drink plenty of fluids during treatment with IMBRUVICA® to help reduce your risk of losing too much fluid (dehydration) due to diarrhea. Tell your healthcare provider if you have diarrhea that does not go away.
- Balance periods of light movement with periods of rest
- Get plenty of sleep, which may include short naps
- Remain well hydrated throughout the day
- Eat a well-balanced diet
- Wash hands often and bathe every day
- Avoid crowds and individuals with contagious diseases
- Do not keep fresh flowers or live plants in your living space
- Do not clean droppings from your pets; have someone do this for you
Infection is a serious possible side effect of IMBRUVICA®. Notify a healthcare professional immediately if signs of infection (eg, fever, chills, weakness, and confusion) occur.1
